Maps

11.0.1 Boundary file

A regional boundary file is downloaded as part of the data pre-processing step and is contained in the object sa_bound.

This can be plotted as a static or interactive map:

Code

ksa_bound |>
    ggplot() +
    geom_sf()

mapview(ksa_bound)

11.0.2 Plot data

Attribute data (e..g area rates) needs to be combined with the boundary data in order to map them. Taking the example of injury….

Code

inj <- read_csv("data/injury_dsr.csv")

11.0.3 Rename regions to link to spatial file

Code

setdiff(inj$region, ksa_bound$ADM1_EN)
